PCIe bandwidth ...will only x4 make a big diff?

[ShazMagwar]

Good day.

I'm looking at getting a 79xx series card. I may have to slap it onto a x16 slot that has only 4 lanes.
I know PCIe b/w's but I can't figure out (for real usage) if the x4 will be a limiting factor...thoughts?

Also, any recommendations on a single slot 7950GT ?
The XFX looks tight

ShaxMagwar,

If I recall correctly, when using PCI-E x4 lanes with a current generation graphics card the drop was only about 5FPS or so. I'll try to check back on that.


eVGA and ASUS are among the manufacturers that produce quality cards.
